I use the Dubro as well....and will look for the "bi-di" (I like that!) next time I am out...

but I think baccus7t is looking for something that is pretty much clear.....

What about clear packing tape?? You may have to cut it into the width you need but it may work...
I do find that with packing tape, a quick clean with some rubbing alcohol helps the tape stick better....
